Compared to amines, amides are very weak bases. While the conjugate acid of an amine has a pK a of about 9.5, the conjugate acid of an amide has a pK a around −0.5. Therefore, compared to amines, amides do not have acid–base properties that are as noticeable in water. This relative lack of basicity is explained by the withdrawing of ...
Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
As both the amine and carboxylic acid groups of amino acids can react to form amide bonds, one amino acid molecule can react with another and become joined through an amide linkage. This polymerization of amino acids is what creates proteins. This condensation reaction yields the newly formed peptide bond and a molecule of water.
Glucosamine. In organic chemistry, an amino sugar is a sugar molecule in which a hydroxyl group has been replaced with an amine group.More than 60 amino sugars are known, with one of the most abundant being N-acetyl-D-glucosamine (a 2-amino-2-deoxysugar), which is the main component of chitin.
Carbohydrates: Foods like whole grains and vegetables that are high in healthy carbohydrates—sugar molecules that provide fuel for the body—are a crucial part of a healthy diet. But much like ...
Dicarbonyls react with amines to produce Strecker aldehydes through Strecker degradation. [18] Acrylamide, a possible human carcinogen, [19] can be generated as a byproduct of Maillard reaction between reducing sugars and amino acids, especially asparagine, both of which are present in most food products.

Glutamine (symbol Gln or Q) [3] is an α-amino acid that is used in the biosynthesis of proteins.Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide.
Fatty acid amides (FAAs) are amides formed from a fatty acid and an amine. In nature, many FAAs have ethanolamine as the amine component. Also known as N-acylethanolamines, they contain the functionality RC(O)N(H)CH 2 CH 2 OH. A well known example is anandamide. Other fatty acid amides are fatty acid primary amides (FAPAs).
